Description

  The present invention is a conduction path device installed in a structural part such as a ceiling or a wall, provided with a frame body comprising at least two frame bodies having sleeve portions surrounding the channel, and at least one sleeve portion is provided with The present invention relates to the conduction path device configured to have a tapered shape so as to form a conical body from one end to the other end. Such conduit devices are used to guide ducts, such as conduits or cable channels, to structural parts such as ceilings or walls, for example, to prevent the spread of fire.

  Such a conduction path device has a frame, and when the building is constructed, it is built in a wall in advance and a place for inserting a conduit is secured. The through space that can be used freely in the frame is only partially used for the insertion of the conduit during the installation of the supply conduit, and therefore the remaining space must be filled after insertion.

In order to form a cutout in the concrete plate, a two-part space holder is placed in the concrete formwork and the concrete is poured into the formwork plate. In some cases, a conical body portion in a two-part space holding body is cut out after a concrete plate is formed and then pulled out. (For example, refer to Patent Document 1.)
Japanese Patent Laid-Open No. 1-271579

  However, in this prior art, there is a defect that the frame body does not exist and the through hole is not stable.

Furthermore, there is a ventilation device for a concrete wall or ceiling constituted by two frames that can be inserted and removed from each other. (For example, refer to Patent Document 2.) The first frame body is provided with two ribs that surround the frame bodies separated from each other in the axial direction, and one of the surrounding ribs is engaged with the end of the second frame body, Both frames are joined together. A flange is provided at the end of the frame opposite to the rib side, and this flange is fixed to the surrounding wall by fixing means.

  However, although this prior art certainly functions as a ventilation duct, it cannot be used as a conduction path through which the conduit is inserted to prevent the spread of fire.

  Accordingly, an object of the present invention is to solve the drawbacks of the conventional conduction path device, to obtain a conduction path device that guarantees a high fire spread prevention function and is easy to assemble.

  In order to achieve this object, the conduction path device of the present invention is provided with at least one insertion body that can be inserted into the channel, provided with a conical body portion in the insertion body, and the conical body portion as the sleeve. It is characterized by having a shape that fits the tapered taper contour of the cone of the part.

  According to this configuration of the present invention, a conduction path device that can be easily closed can be prepared, and the conduit can be inserted by opening as necessary. Also, the installation property of the conduction path device is good.

  In a preferred embodiment of the present invention, a gap layer made of an inflatable gap material is provided on the outer surface of the conical portion of at least one insert, and the channel is smoked when closed with the insert. Be gas tight. As an alternative, the gap filling layer can be made of an elastic sealing material that does not expand.

  In order to completely block the channel, it is preferable to provide a plurality of inserts. According to this configuration, the channel can be partially opened by removing one or more plugs and a conduit can be passed through the channel.

  In a preferred embodiment, at least one flange is provided at one end of the at least one insert so that the insert can be supported on the edge or flange of the frame, or For example, it is possible to fix to the opposing flange portions of the frame by screw means.

  In a preferred embodiment of the invention, the interior space of at least one plug is filled with an inflatable gap filling material. According to this configuration, when a fire occurs, additional sealing of the channel can occur, and loss of the plug can be avoided.

  Furthermore, in another preferred embodiment of the invention, the internal space of at least one plug is filled with an inorganic structural material. According to this configuration, the conduction path device can support a large load, and when the fire occurs, the loss of the insertion body can be avoided.

  At least one plug is provided with a handle. According to this configuration, the user can easily grasp the insertion body, and can easily pull out or fit the frame body.

  Furthermore, it is preferable to provide another insertion body provided with a conduit penetration path in advance. At the time of assembling the conduit, the plug for closing the channel is removed from the frame, and the plug having a conduit penetration path is inserted. An assembly conduit can be connected to the conduit penetration. The assembly of this conduit and conduit passage in the component greatly improves the workability.

  Next, preferred embodiments of the present invention will be described with reference to the drawings.

  1 to 3 includes a frame body 11 having a rectangular cross section through which a channel 31 passes. The frame body 11 is constituted by a first frame body portion 12 and a second frame body portion 13. . The frame portions 12 and 13 have sleeve portions 14 and 15, respectively. The sleeve portion 14 of the first frame body portion 12 is formed into a conical body having a tapered taper from one end portion 18 provided with the flange portion 16 toward the other end portion 19. Similarly, a flange portion 17 is provided at one end of the second frame portion, and a sealing element 29 is provided on the side surface of the flange portion opposite to the sleeve portion 15 side. The conduction path device 10 further includes a plurality of insertion bodies 20. Each of these inserts 20 has a cone portion 21 and two flange portions 22. The cone portion 21 is adapted to the tapered cone shape of the sleeve portion 14 of the first frame portion 12. The flange portion 22 protrudes from one end portion of the conical body portion 21. The interior space 23 of the insert 20 is filled with a lightweight or heavy noncombustible material, for example, an inorganic material such as concrete or cement, or an inflatable gap material. The outer surface 25 of the conical body portion 21 is covered with a gap layer 26 made of an elastic sealing and expanding gap material. The insert 20 is further provided with a handle 24.

  For example, when forming a structural portion 30 such as a concrete ceiling, the frame 11 of the conduction path device 10 is fixed in at least one concrete mold, and the concrete element is formed by the sealing element 29 of the frame 11. The gap is filled. The sleeve portion 14 of the frame body portion 12 is inserted into the sleeve portion 15 of the frame body portion 13 in advance. After the concrete is poured into the mold and hardened, the conduction path device 10 is fixed in the structural part 30, in particular fixed by flange parts 16, 17, which are evident from FIG. 3. As such, it engages with the opening edge of the structural portion 30.

  The channel 31 of the frame body 11 is closed by the insertion body 30, and the insertion body 30 is inserted into the frame body portion 12 having the tapered cone-shaped sleeve portion 14 (see FIG. 3). The insertion body 20 can be screwed to the frame body 11 at the flange portion 22 to ensure fixation. The channel 31 can be hermetically sealed by the gap layer 26 formed of an elastic sealing gap material. To conduct the conduit 40 to the structural portion 30, one or more plugs 20 at the required location are removed from the channel. A special insertion body 41 is inserted into the free space of the channel 31, and a conduction path 42 for the conduit 40 is provided in the insertion body 41 in advance (see FIG. 4). This insert 41 substantially corresponds to the outer contour of the insert 20, is provided with a similar flange 22, and ensures a smoke gas tight and fire spread preventing passage through the structural part 30 through the conduit 40. As an alternative, the conduit is directly inserted into the free space of the channel 31 and the gap between the conduit in the channel 31 is filled with a gap filling material, for example in the form of foam material, to create a new smoke gas tightness in the channel 31.
